Selecting lighting devices based on an indicated light effect and distances between available lighting devices

Abstract

A method of controlling one or more lighting devices to render a light effect comprises obtaining (101) distance information indicative of distances between a plurality of lighting devices, receiving (103) an input signal indicative of the light effect, selecting (105) a set of lighting devices from the plurality of lighting devices based on the light effect and the distances, wherein a first set of multiple lighting devices is selected if said light effect is a moving light effect and a second set of multiple lighting devices is selected if said light effect is a non-moving light effect, said second set of lighting devices being larger than said first set of lighting devices, said moving light effect being a light effect that moves across multiple lighting devices, and controlling (107) only the selected set of lighting devices to render the light effect.

 at least one input interface;   at least one transmitter; and   at least one processor configured to:
 obtain distance information via said at least one input interface, said distance information being indicative of distances between a plurality of lighting devices, 
 receive an input signal indicative of said light effect, 
 select a set of lighting devices from said plurality of lighting devices based on said light effect and said distances, wherein a first set of multiple lighting devices is selected if said light effect is a moving light effect and a second set of multiple lighting devices is selected if said light effect is a non-moving light effect, said second set of lighting devices being larger than said first set of lighting devices, said moving light effect being a light effect that moves across multiple lighting devices, and 
 control, via said at least one transmitter, only said selected set of lighting devices to render said light effect. 
   
     
     
         2 . A system as claimed in  claim 1 , wherein said second set comprises all lighting devices of said plurality of lighting devices. 
     
     
         3 . A system as claimed in  claim 1 , wherein said at least one processor is configured to select said set of lighting devices from said plurality of lighting devices such that for each of said set of lighting devices, a distance between said respective lighting device and at least one other lighting device of said set of lighting devices does not exceed a proximity threshold. 
     
     
         4 . A system as claimed in  claim 1 , wherein said at least one processor is configured to:
 obtain further distance information via said at least one input interface, said further distance information being indicative of a user-perceived distance between a user and said plurality of lighting devices, and   select said set of lighting devices from said plurality of lighting devices further based on said user-perceived distance between said user and said plurality of lighting devices.   
     
     
         5 . A system as claimed in  claim 1 , wherein said at least one processor is configured to:
 obtain device type information indicative of device types of said plurality of lighting devices, and   select said set of lighting devices from said plurality of lighting devices further based on said device types of said plurality of lighting devices.   
     
     
         6 . A system as claimed in  claim 1 , wherein said at least one processor is configured to:
 obtain a dynamic input signal, said dynamic input signal being indicative of values of one or more environmental parameters over time, and   determine consecutive light effect parameter values for said light effect based on said values of said one or more environmental parameters.   
     
     
         7 . A system as claimed in  claim 6 , wherein said one or more environmental parameters comprise at least one of a detected activity, a detected motion, a detected sound property, a detected sound level, and a detected number of people. 
     
     
         8 . A system as claimed in  claim 6 , wherein said at least one processor is configured to determine for said light effect a first set of light effect parameter values if an environmental parameter value indicated in said dynamic input signal exceeds a parameter threshold or a second set of light effect parameter values if said environmental parameter value indicated in said dynamic input signal does not exceed said parameter threshold, said first set of light effect parameter values being different from said second set of light effect parameter values. 
     
     
         9 . A system as claimed in  claim 1 , wherein said at least one processor is configured to:
 obtain a content signal comprising audio and/or video content, and   determine consecutive light effect parameter values for said light effect based on said audio and/or video content.   
     
     
         10 . A system as claimed in  claim 9 , wherein said at least one processor is configured to:
 obtain further distance information via said at least one input interface, said further distance information being indicative of a user-perceived distance between said plurality of lighting devices and a media rendering device rendering said audio and/or video content, and   select said set of lighting devices from said plurality of lighting devices further based on said user-perceived distance between said plurality of lighting devices and said media rendering device.   
     
     
         11 . A system as claimed in  claim 1 , wherein said at least one processor ( 5 , 45 , 55  is configured to determine or adjust values of one or more light effect parameters of said light effect based on said distances. 
     
     
         12 . A system as claimed in  claim 1 , wherein said at least one processor is configured to:
 obtain position information via said at least one input interface, said position information being indicative of positions of said selected set of lighting devices, and   determine or adjust values of one or more light effect parameters of said light effect based on said positions.   
     
     
         13 . A method of controlling one or more lighting devices to render a light effect, said method comprising:
 obtaining distance information, said distance information being indicative of distances between a plurality of lighting devices;   receiving an input signal indicative of said light effect;   selecting a set of lighting devices from said plurality of lighting devices based on said light effect and said distances, wherein a first set of multiple lighting devices is selected if said light effect is a moving light effect and a second set of multiple lighting devices is selected if said light effect is a non-moving light effect, said second set of lighting devices being larger than said first set of lighting devices, said moving light effect being a light effect that moves across multiple lighting devices; and   controlling only said selected set of lighting devices to render said light effect.   
     
     
         14 . A computer program product for a computing device, the computer program product comprising computer program code to perform the method of  claim 13  when the computer program product is run on a processing unit of the computing device.
